Erythrulose

What: Erythlurose is a ketone sugar commonly found in raspberries. It is also a key active ingredient for natural self-tanners, most often combined with Dihydroxyacetone. Erythrulose, like Dihydroxyacetone, reacts with the amino acids in the keratin protein on the outer layer of skin. The nontoxic reaction creates a color change in the skin, similar to a cut apple exposed to oxygen, and gives the appearance of an actual sun tan. This tanned effect sloughs away gradually over the course of 3-10 days.

Origin: Erythrulose is obtained through the fermentation of Erythritol, a sugar alcohol found in red raspberries and other red berries.
